| Abstract Scope |
Dental restorative composite (DRC) reinstalls occlusal functions of the patients who suffer edentulism and therefore is one of the most important dental materials. To fulfill the strict biomedical and aesthetic requirements, the materials choices of DRC are limited. How to enhance the fracture resistance of DRC with limited materials choices? This is a critical question in the area.
This talk introduces the authors’ recent progress on the design of fracture resistant DRC. Learning from nature, a graded DRC structure was fabricated by zirconia nanoparticle reinforced resin-based polymers. State-of-the-art characterization techniques were adopted to verify the morphology, topology and distribution of mechanical properties of the structures. Standardized flexural experiments were carried out under both monotonic and cyclic loadings on both bio-inspired DRC and control groups. Experimental results demonstrated that, bio-inspired DRC showed significantly higher fracture resistance under monotonic loading and much lower failure rate under cyclic loading than conventional DRC. |
